Thanks for the replies guys.
I should have clarified they are for YB pistons that I am reusing in a freshly honed block.
SFE,
I have a set of Total Seals here left over from the last build so I may use them but was looking at using standard OEM style rings. I guess I'll just order a set via Brands Hatch or Burtons. I try and support local business when I can.
I am using special Piston Services 92mm forgies in another motor. I was given a choice of Hastings rings or total seals and interestingly the rings they used are EJ20T items. At least it makes replacements easy.
